One-coat, waterproof surface membrane.
A solvent-free, two-part, one coat, epoxy resin system which chemically cures to provide a surface membrane for suppressing rising dampness and residual construction moisture in concrete and sand/cement screeds (up to 92% RH).
Not suitable for:
Rough surfaces must be smoothed using Stopgap Green Bag and Liquid smoothing underlayment and allowed to dry for 12 hours (minimum) before applying waterproof membrane. When Stopgap Green Bag is used under a Stopgap Waterproof Surface Membrane, absorbent concrete and sand/cement screeds must be primed first with Stopgap P131 diluted 1:7 with water.
A coat of undiluted Stopgap P131 General Purpose Neoprene Primer must be applied after the surface membrane has cured, and before applying a smoothing underlayment.
Power floated floors can be shot blasted to assist adhesion.
Stopgap F76 is pigmented to allow visual control of the coverage.
